Abstract
Open a kind of PC/ABS alloy of the present invention and preparation method thereof, it is characterised in that: this alloy is made up of each component of following percentage by weight: PC/ABS:70% 95%, the PA6:5% 30% containing mineral powder；PC content in described PC/ABS is 50% 80%, in the described PA6 containing mineral powder containing 20% 40% mineral powder, and the particle diameter of mineral powder is nano-scale range.The content of PC in conservative control PC/ABS of the present invention, and the content of PA6 Minerals powder, why higher being because of the content control of PC in PC/ABS, PC content is the highest, the plating performance of PC/ABS material is the poorest, but the mechanical property of material is the strongest, and the invention add, with PA6, the plating performance that mineral powder strengthens the PC/ABS material of this high PC content cleverly.
Description
Technical field
The present invention relates to PC/ABS technical field of alloy, be specifically related to a kind of PC/ABS alloy and preparation method thereof.
Background technology
Merlon (PC) and acrylonitrile-butadiene-styrene (ABS) (ABS) plastics can prepare PC/ABS alloy plastic, this
Plant alloy plastic to combine the excellent properties of bi-material, the i.e. processability of ABS material and the mechanical property of PC and heatproof, resist
The character such as ultraviolet, can extensively apply on automotive interior parts, Business Machine, the communication apparatus, electrical home appliances and luminaire again.
And these PC/ABS alloys characteristic due to performance and the characteristic of application, need to carry out electroplating processes；And the plating of plastics
Not only technics comparing is complicated, and the requirement to plastic basis material is higher, and the surface property of base material is very big on electroplating effect impact,
Additionally, plating performance also can be impacted by the composition of base material.
At present, the PC/ABS material of prior art, in the process using the roughening of chromic acid chemistry, although butadiene therein is
Rubber bodies is oxidized easily corrosion, leaves the most small hole on continuous print resin-phase surface, it is achieved the plating of electroplating process
Combination between layer and base material, but this single hole adhesion still has certain deficiency, uses process also in the later stage
Can a certain degree of generation causing craze of coating, obscission.
Summary of the invention
The technical problem to be solved is, the shortcoming overcoming above prior art: provide a kind of plating performance good,
The PC/ABS alloy that electrodeposited coating is the most easy to crack, come off.
The technical solution of the present invention is as follows: a kind of PC/ABS alloy, this alloy is by each group of following percentage by weight
It is grouped into: PC/ABS:70%-95%, containing the PA6:5%-30% of mineral powder；PC content in described PC/ABS is
50%-80%, contains the mineral powder of 20%-40%, and the particle diameter of mineral powder in the described PA6 (nylon 6) containing mineral powder
For nano-scale range.
As preferably, mineral powder of the present invention can be in Talcum, wollastonite, silica flour, titanium oxide and zinc oxide
One, or the mixing of more than one arbitrary proportions；Particle diameter is 1-100nm.
As preferably, the PC/ABS alloy that the present invention is above-mentioned, this alloy is made up of each component of following percentage by weight:
PC/ABS:75%-90%, containing the PA6:10%-25% of mineral powder；PC content in described PC/ABS is 55%-75%,
The described PA6 containing mineral powder contains the mineral powder of 25%-35%, and the particle diameter of mineral powder is nano-scale range.
As preferably, PA6 of the present invention is plating level PA6, can be such as 73M40, BG30, D121-GF15,
Akro B3GK50, EMS BG6-BK, BM 240H1.0, BASF B3S, Bayer BM240H2.0, You Nijisi A1030GFLBK,
One or more mixture of EMS BG30/2BK).
The present invention also provides for the preparation method of a kind of above-mentioned PC/ABS alloy, and concrete steps include:
(1) first raw material PC, ABS and the PA6 containing mineral powder are dried, dry temperature and be 95-100 DEG C, the time
For 4-8 hour；
(2) raw material after then drying adds in double screw extruder according to formula proportion, is 185 at extrusion temperature
DEG C-260 DEG C, screw speed is to carry out batch mixing extrusion under conditions of 200-600rpm, it is thus achieved that target product.
The present invention adding before double screw extruder, is divided into two feed hoppers and feeds, this is because PC/ABS and containing
Having PA6 both raw materials of mineral powder, its density of material is different, two feeding hoppers, feeding hopper FREQUENCY CONTROL at 55-65 hertz,
Bi-material charging can be substantially ensured that uniformly.
Advantages of the present invention and beneficial effect:
1. the present invention adds PA6 and the mineral powder of plating grade first in PC/ABS material；So can be achieved with electricity
The reinforcement of plating performance, is primarily due to: in PC/ABS, butadiene is rubber bodies, can be roughened by chromic acid, forms hole, thus convenient
Plating Stromal Precipitation attachment；Plating level PA6 itself possess plating performance (PA6 base material and mineral powder due to incompatible exist tiny
Plating crystallization apposition growth is easy in gap)；There is incompatibility with plating level PA6 containing mineral powder in PC/ABS, is blended
There is small thin trace in rear product material, contributes to electroplating substrate adventitious deposit；Above 3 combine and strengthen the electricity of PC/ABS
Plating performance.
The content of PC in conservative control PC/ABS the most of the present invention, and the content of PA6 Minerals powder, why PC/ABS
Higher being because of the content control of middle PC, PC content is the highest, and the plating performance of PC/ABS material is the poorest, but the power of material
Learn performance the strongest, and the adding mineral powder with PA6 cleverly and strengthen the PC/ABS material of this high PC content of the invention
The plating performance of material.
